Phytoremediation is the use of plants to treat environmental
problems, such as contaminated soils, without excavating the contaminant
material and disposing of it elsewhere. The
plants able to accomplish this mitigate the concentrations of the pollutant is
contaminated soils, water, or air contain, degrade, or even eliminate the contaminants
from the media. The contaminants that
can be mitigated in this fashion include metals, pesticides, solvents,
explosives, crude oil and its derivatives.
Phytoextraction is a sub-process of phytoremediation. This sup-process uses trace element-accumulating
plants to concentrate the contaminant in the plant’s tissues. The contaminants are then removed from the
medium by harvesting the plant.
